Specifications

N/A Product information mentioned in the technical datasheet is given for information purposes and can differ from requirements of specifications above. In that case, customer requirements are valid for your application.

Flash Point

N/A XS4201 Base: 24ºC (75ºF)
XS4201 Hardener: 170ºC (338ºF) Gloss levels have been determined using glossmeter with an angle of incidence of 60º. The theorical consumption value doesn’t take into account the transfer efficiency for spray application

Instructions for Use (Spray Application)

N/A Mixing ratio by volume - Base 2 V
Mixing ratio by volume - Hardener / Catalyst 1 V
Mixing ratio by volume - Water 0.5 V to 1 V

Mixing Procedure
Ideally, the unmixed products should be stored between 18ºC and 25ºC (64ºF and 77ºF) for 24 hours before use.
The XS4201 base should be mixed for 5 minutes in a pneumatic or oscillating mixer before use.
Mix the base, hardener and thinner until the mixture is homogenous.
PThe mixture must be made at a temperature between 15ºC and 35ºC (59ºF and 95ºF).
Remark : It is recommended to sieve the mixture using a 125-190 µm (4.9-7.5 mils) filter.
For gray and black colors, 0.5v dilution is recommended.
For white and bright colors, 1V dilution is recommended.
